Greetings all, my first day in Big School

Been using MSO for many years and thought I could figure my way around it quite comfortably.
However, recently I have been working on some spreadsheets and have been attempting a few rather complex functions.
As they say, when all else fails, read the instructions! So I bowed to my own pressure and hit the search engine. And found this!!

Awesome forum, I have already learned so much just from reading a few posts. Where have you all been all my life ???

Extremely happy to be here, thank you.
